The GZD(W) series (microcomputer-controlled) DC power cabinets are a new-generation replacement product developed in response to the requirements for DC power cabinets in unattended substations.
Overview
The GZD(W) series (microcomputer-controlled) DC power supply cabinet is a next-generation replacement product developed in response to the requirements for DC power supply cabinets in unattended substations. It is suitable for large, medium, and small power plants and substations, providing the DC power required for high-voltage switchgear operation (closing and opening), relay protection, automatic control, emergency lighting, and other applications under both normal operating conditions and fault conditions.
Model and Meaning
Functional Features
◆ Automatic switchover between two AC input sources to ensure normal system operation;
◆ Ultra-wide input voltage range, ensuring strong grid compatibility and suitability for use in relatively harsh environments;
◆ Employs high-frequency switching power supply technology, features a modular design with N+1 hot redundancy, and delivers high reliability;
◆ The rectifier module supports hot-swapping, making routine maintenance convenient and efficient.
◆ The charging module employs cutting-edge international software-switching technology, delivering high conversion efficiency and minimal electromagnetic interference.
◆ Hardware-based, low-difference, self-regulating current-sharing technology, with a typical output current imbalance of ±3% between modules;
◆ Monitoring can be configured with LCD screens or touchscreens, featuring a user-friendly and comprehensive interface for simple and convenient operation;
◆ Real-time monitoring enables comprehensive surveillance and control of system operation, supporting system configuration and information retrieval. Additionally, through backend and remote monitoring, the system can implement the “four remotes” functions—remote measurement, remote control, remote signaling, and remote adjustment—thereby achieving unattended operation.
◆ The monitoring system automatically and precisely manages battery voltage, charge/discharge current, and temperature compensation, while providing over- and under-voltage alarms, over-temperature alerts, and fault alarms to ensure the battery operates under optimal conditions and to extend its service life.
◆ Equipped with manual and automatic voltage regulation functions, as well as branch circuit insulation detection functionality;
◆ Reliable lightning protection and high-level insulation safeguards ensure the safety of the system and personnel;
◆ Offers two communication interfaces—RS232 and RS485—and three communication protocols to choose from: RTU, CDT, and MODBUS.
◆ Equipped with expansion interfaces for connecting to external devices.Main Technical Parameters
